8. An attachment for sewing machines comprising a strip-guide having arelatively wide run for guiding the relatively wide side strip portionot a hat-lining, vand other relatively narrow communicating runs forguiding a folded insert strip portion adjacent one edge of the sidestrip portion, a cord guide intermediate the runs for said insert stripportion, and an edge-guide disposed between the projected boundary linesof the narrow runs.

9. rlhe combination with a sewing machine having a reciprocating needle,feeding mechanism, and a presser-toot, of an edgeguide, and astrip-folder comprising spaced walls deiining an-shaped passageway, saidfolder and edge-guide being so related to one another and to the needleand pressertoot that the edge-guide lies between parallel lines deiinedby the edges ot the upper ply ot the folded strip passing through thefolder, and that the needle lies between par'- allel lines defined bythe edge-guide and the tree edge of the upper ply of said folded strip.
